Wow, what reactions! Alinco makes a small switching supply for 30 amps in a form factor roughly of an external hard drive. Has a switching freq adjustment. Works FB, and I haven't had to use the frequency change knob once. I did try to find spots where it interfered, no luck. It sits about 3 inches above my rig, no problem.

I suspect the real reason for the adjustment is that plenty of Hams and others hate switchers in general. The addition of adjustment is probably to entice people who might otherwise dismiss the supplies outright.
